ICE-CREAM FREEZER.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed August 15, 1919. Serial No. 317,747.

To all whom it may concern:

Be it known that 1, JOHN G. Gmns, a citizen of the United States, residing in the city and county of Lancaster, State of Pennsylvania, have invented a new and useful Ice-Cream Freezer, of which the following is a specification.

My invention consists of improvements in an ice cream freezer as will be hereinafter described. and definitely pointed out in the claims.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are Within the spirit or scope of the claims.

Figure 1 represents a top or plan View of an ice cream freezer embodying my invention.

Fig. 2 represents a central vertical section on line 52-52 Fig. 1.

Fig. 3 represents a horizontal section of a portion on line 3-3 Fig. 2.

Fig. 4 represents a to plan view of a por tion of the can of the Freezer.

Fig. 5 represents a bottom plan of the bridge of the device.

Fi 6 represents a vertical section of a detac ed portion.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates the can of the freezer, and 2 designates the dasher therein, and 3 designates the tub or pail, which members eX- cepting the features of my invention ap plied thereto are of usual construction.

The can is mounted on the step 4 on the bottom of the tub whereby said can may be rotated thereon. The dasher is mounted on the step 5 on the bottom of the can whereby it is supported thereon, it being understood that the can revolves around the dasher and the latter will be held stationary by means as will be hereinafter described.

6 designates the cover of the can, the same having on the top thereof centrally thereon the pinion 7 in which is a vertically arranged circular opening or bore 8. the latter being in communication with the circular opening 9 in the cover 6 of the can.

10 designates a bridge which at one end is hinged as at 11 to the top of the tub 3 and opening 8 in the pinion 7 and consequently with the opening 9 in the cover 6 of the can.

Rising from the top of the dasher 2 is the tongue 1-1 which is passed through the opening 9, the opening 8, and slot 13, said tongue being fiat in form, and said slot being similarly shaped whereby as the bridge is stationary and receives said tongue in said slot has been stated, the dasher is held stationarily while the can rotates around the same.

15 designates a crank handle whose limb 1G is mounted on the bearing 17 on the bridge 10, passes through the latter and has on its lower end which is below said bridge the spur wheel 18 which entering the tub is adapted to engage the pinion 7.

The operation is as follows The crank handle is operated whereby it imparts rotation to the spur wheel and consequently to the pinion 7, thus rotating the can in which the ice cream mixture had been duly placed and the tube suitably iced, the ice cream will be easily and quickly produced. When this is accomplished the bridge is unlocked and raised when the spur wheel 18 follows the same and so removes from the pinion 7 the bridge also clearing the tongue H. Then the cover of the can may be removed when the contents of the can are accessible, for further action usual in such cases.

The cover 6 is removably interlocked with the top of the can so that the latter will rotate with said cover by means of the interengaging depressions 19 in the sides of the can of the rim of the cover, as most plainly shown in Fig. 3.

Secured to the underside of the bridge is the plate 20 in which is a slot 21 which registers with the slot 13 and serves to reinforce said bridge about said slot 13, the walls of which latter are subjected to strain owing to their embracing action. of the tongue 1-1 to hold the dasher stationary.

When the catch 12 is released and the bridge 10 raised it turning on its hinge 11, the spur wheel 18. crank handle 15 and the bearing 17 follows said bridge, they being fixtures of the latte-1'. VVhen the bridge is returned to its operative position the spur Lil wheel 18 intermcshcs with the pinion 7 and is ready to operate the latter by the action of the crank handle 15.

The pinion 7 is attached to the cover of the can by the sleme which is fitted in the bore 8 of the pinion and secured thereto, and has its lower end swaged or otherwise ii engaged with the wall of the open ing. The bearing 17 for the limb 16 of the crank handle consists of a plate bent arch shaped having in its crown an opening to receive freely the upper portion of said limb iii, the lower portion of the latter passing freely through an opening in the bridge 10 thus steadily supporting said limb at different places. The limbs of said bearing are passed through openings in the bridge and provided with feet which are turned horizontally on the underside of the bridge and tired thereto, thus holding said bearing firmly connected with said bridge and preventing wabbling and rattling of the crank handle and the spur wheel 18.

The reinforcing plate 20 for the bridge 10 about the slot 13 therein serves also to assist in retaining the pinion 7 in position and prevents the same from rising, and like wise preventing the cover 6 of the can from upward disconnection and upward bulging of the bridge 10.

As the pinion 7 is secured to the sleeve 22 and the lower end of the latter is flanged and so engages the underside of the cover 6, see Fig. 6, a strong connevtion is provided for said sleeve and pinion with said cover, and said pinion and sleeve are prevented from slipping around on said cover.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In an ice cream freezer, a rotatable can, a dasher stationaril' therein, a tub, a bridge removably connectible with said tub and adapted to control said dasher against rotation, a gear wheel on the cover of said can secured thereto, a crank handle having a bearing on said bridge, a gear wheel on said handle, said gear wheel removably intermeshing with said pinion, and means on said bridge adapted to interlock the latter with said tub and retain said gear wheel and pinion in engagement, said bearing for the crank handle consisting of a plate substantially archshaped having one limb of said crank handle mounted in the crown thereof and having its leg portions mounted on said bridge and provided with laterally turned feet which are secured to the latter.

2. In an ice cream freezer, a can, a cover therefor, a dasher, a gear Wheel on said cover, a movable bridge in said tub, a crank handle mounted on said bridge, a reinforcing plate on said bridge about the wall of the slot therein, and a gear wheel on said handle, said gear wheels being adapted to intermesh, said dasher having an upwardly extending flat tongue, said gear wheel on said cover having a circular bore in which said flat tongue is received, said bridge having therein a slot,and said reinforcing plate having therein a slot, said slots conforming to said fiat tongue and being in register with said bore.

3. In an ice cream freezer, a tub, a bridge thereon, a rotatable can, a stationary dasher in the latter, a pinion on the cover of :said can, a tubular sleeve on the cover of the can, said pinion having a bore in its hub portion and fitted on and secured to said sleeve, a spur wheel on said bridge adapted to mesh with said pinion, an upwardly extending flat tongue on said dasher adapted to pass through said cover, pinion and bridge, the latter having therein a slot adapted to receive said tongue and embrace the same, and a reinforcing plate on said bridge having therein a slot which is adapted to register with the slot in said bridge, both slots being adapted to register with said bore.
